I haven't seen my cleaner shrimp all day. The last I saw him was last night before the tank lights went off. I only have some hermits in my tank. Could they kill it and eat ALL the remains? I moved all rock and searched... I couldn't even find anything to show he was killed (parts) He always comes out when I stick my hand in the tank or for feedings. I don't have anything he could get stuck in or sucked up into. It's a small tank. He shed about 2 or 3 days ago so he wasn't due. Has anyone had crabs kill a shrimp??
